Hydraulic rocket

Abstract

A hydraulic rocket includes a main body having a first end, a cylindrical mediate section and a tapered second end, a warhead mounted on the first end of the main body, a rear skirt mounted on the second end of the main body, and a nozzle mounted on the second end of the main body and rested on the rear skirt to position the rear skirt on the second end of the main body. Thus, the rear skirt and the warhead are directly mounted on the main body without needing to provide any bonding agent, so that the hydraulic rocket can be assembled easily and conveniently, thereby facilitating the user assembling the hydraulic rocket.

1 . A hydraulic rocket, comprising: 
 a main body having a first end, a cylindrical mediate section and a tapered second end;    a warhead mounted on the first end of the main body;    a rear skirt mounted on the second end of the main body; and    a nozzle mounted on the second end of the main body and rested on the rear skirt to position the rear skirt on the second end of the main body.    
     
     
         2 . The hydraulic rocket in accordance with  claim 1 , wherein the main body is made of elastic plastic material.  
     
     
         3 . The hydraulic rocket in accordance with  claim 1 , wherein the second end  42  of the main body  4  has a distal end formed with a threaded connector having a periphery formed with an annular resting flange, and the rear skirt has an inner wall formed with a plurality of reinforcement ribs rested on the resting flange of the main body.  
     
     
         4 . The hydraulic rocket in accordance with  claim 3 , wherein the nozzle has an inner wall formed with an inner thread screwed on the threaded connector of the main body, so that the nozzle is secured on the threaded connector of the main body.  
     
     
         5 . The hydraulic rocket in accordance with  claim 3 , wherein each of the reinforcement ribs  64  of the rear skirt  6  has an arcuate tapered shape.  
     
     
         6 . The hydraulic rocket in accordance with  claim 5 , wherein each of the tapered reinforcement ribs  64  of the rear skirt  6  has a maximum diameter greater than the diameter of the resting flange  431  of the main body  4  and has a minimum diameter smaller than the diameter of the resting flange  431  of the main body  4 , so that each of the tapered reinforcement ribs  64  of the rear skirt  6  is closely rested on the resting flange  431  of the main body  4 .  
     
     
         7 . The hydraulic rocket in accordance with  claim 1 , wherein the first end of the main body is formed with a connecting portion having a periphery formed with an annular locking groove, and the warhead has an inner wall formed with an annular locking flange locked in the locking groove of the main body.  
     
     
         8 . The hydraulic rocket in accordance with  claim 7 , wherein the connecting portion of the main body has a substantially semi-spherical shape.  
     
     
         9 . The hydraulic rocket in accordance with  claim 7 , wherein the warhead is forced onto the connecting portion of the main body in a close fit manner.  
     
     
         10 . The hydraulic rocket in accordance with  claim 1 , wherein the rear skirt is a hollow barrel.  
     
     
         11 . The hydraulic rocket in accordance with  claim 1 , wherein the rear skirt has a tapered inner wall to mate with the tapered second end of the main body so that the rear skirt is closely rested on the second end of the main body.  
     
     
         12 . The hydraulic rocket in accordance with  claim 1 , wherein the rear skirt has an outer wall integrally formed with a plurality of stabilizing fins.  
     
     
         13 . The hydraulic rocket in accordance with  claim 1 , wherein the rear skirt has an outer wall having a diameter equal to that of the mediate section of the main body.  
     
     
         14 . The hydraulic rocket in accordance with  claim 1 , wherein the rear skirt has an outer wall having a diameter smaller than that of the mediate section of the main body.
